8. Valve schematic examples
The following examples incorporate parametric numbering (table 7 ), enabling all the operating cases corresponding to the successive adsorption of the various adsorbers present to be represented with a single graph. Thus, for the PSA N 2 , VSA O 2 and PSA H 2 cycles presented here, we use the following tables, whose dimension depends on the number of adsorbers considered:
Passing from line to line, the PLC can then assign to each parameter "a" to "j", the number corresponding to the current phase time.
for a PSA H 2 with 10 adsorbers, at the fourth current...
